The recovery rate of early stuttering

PurposeAcross studies there is great variability in reported rates of stuttering recovery. This study examined the impact that different definitions of recovery had on calculation of recovery rates and factors associated with recovery within the same sample of children.MethodSpeech samples and parents and child reports of their experiences of stuttering were collected from 38 children who stuttered aged 2–5 years of age (Occassion-1) and again at 9–13 years of age (Occassion-2). Four different criteria for recovery that were developed representing variations in criteria reported in previous research were applied to data from these children.Results. The majority of the participants (82%) showed very little disfluent speech (<1% syllables stuttered) at Occasion 2. Recovery rate varied greatly depending on the criteria used, ranging from 13.2%–94.7%. Definitions ordered from least to greatest recovery that were (a) parent and clinician report no stuttering and no stuttering observed (13.2 %); (b) ≤1% syllables stuttered; severity rated at ≤1; parent, clinician, and child report recovery (55.3 %); (c) ≤1% syllables stuttered; severity rated at ≤1; parent and clinician report recovery (71.1 %); (d) <3.0 % syllables stuttered (94.7 %). Five participants were considered recovered and two were considered persistent stutters across all criteria. Different factors were associated with recovery from stuttering depending on the criterion used.ConclusionThe concept of recovery from stuttering is complex and estimations of recovery rate are likely to be greatly affected by differences in definitions and measurement across studies. This has a flow-on effect in determining the factors associated with recovery from stuttering.     

The mediating mechanisms underlying the longitudinal effect of trait anger on social aggression: Testing a temporal path model

Social aggression is widely emerging among young adults and can cause social and psychological adjustment problems. Although trait anger is believed to affect aggression, the longitudinal effect of trait anger on social aggression has not been tested, and the underlying mechanisms are unclear. A temporal path model (TPM) was constructed to explain how trait anger longitudinally predicts social aggression. Three-wave data were collected in five provinces of China from 1209 valid young adults. The results showed that trait anger predicts social aggression through both hostile attribution tendency (an in-process tendency) and anger rumination tendency (a post-process tendency), and these tendencies may predict each other. The present study supports the idea of TPM for aggression and develops General Aggression Model.     

Methodological considerations for longitudinal investigations of young drivers

IntroductionMotor vehicle crashes (MVCs) are the leading cause of mortality among teenagers. Teen driving research has a longstanding history; however, much of this work is cross-sectional. The Eunice Kennedy Shriver National Institute for Child Health and Human Development funded a study, REACT (Roadway Experiences and Attentional Change in Teens) which combined factorial and longitudinal designs to investigate the independent and joint effects of age and driving experience on driving attention over time among young drivers.MethodLongitudinal methods offer important contributions to teen driving research by enabling characterization of driving trajectories. This paper describes methodological considerations for longitudinal studies of teen drivers. Such considerations are organized into overarching themes, including population, recruitment, enrollment, and retention, throughout this paper. These considerations were compiled as a combination of our own experiences in REACT and previous literature. We elaborate on these considerations below to illustrate the value of each consideration.ResultsIssues encountered are discussed and strategies for dealing with various issues are described. Transportation barriers, scheduling difficulties, and skipped study milestones were among the most frequent challenges; we outline these and other issues encountered in REACT and corresponding considerations for such issues in Table 2. Sharing these experiences should aid future longitudinal investigations of young drivers, which are critically needed to reduce teen MVCs.ConclusionsStudies similar to REACT are considerable undertakings due to the comprehensive nature of longitudinal design. Such investigations must maintain a delicate balance between appropriate amounts of rigor and flexibility in the development of thoroughly defined research questions and theoretically driven frameworks. Key considerations that have contributed to the success of REACT are outlined, challenges encountered throughout data collection are documented, and recommendations based on choices made and lessons learned to inform future longitudinal investigations on young drivers are provided.     

Longitudinal relations between psychological distress and moderate-to-vigorous physical activity: A latent change score approach

ObjectivesThe effect of physical inactivity on mental health risk is well established; however, less is known about about how psychological distress might deter participation in physical activity. Guided by advancements in the treatment of longitudinal data, the aim of this study was to examine patterns and predictors of change in moderate-to-vigorous physical activity (MVPA) and psychological distress (e.g., feeling nervous, worthless).Design methodAustralian adults (4944 females, M_age = 34.63 years ±5.34; 4322 males, M_age = 37.51 years ±6.14) provided baseline data as part of the Longitudinal Study of Australian Children (LSAC) and were followed for measurements every two years for 10 years.ResultsLatent change score analyses revealed support for a reciprocal effects model, whereby change in MVPA and psychological distress occurred as a function of individuals’ prior levels of, and/or prior change in these variables.ConclusionsThis investigation is the first to document that changes in MVPA and psychological distress are coupled temporally. Notably, we observed that individuals’ distress levels at a given time point predicted subsequent change on both MVPA and distress; a finding which provides novel and important insight into how adults’ activity levels and psychological distress fluctuate relative to one another.     

Characterizing positive and negative ‘voicers’ in elite sport teams: The role of the Five Factor Model and narcissism in players’ frequency and passing on of voice

ObjectiveThis study examined the role of the Five Factor Model and grandiose narcissism in players’ positive (i.e., constructive voice, supportive voice) and negative voice (i.e., defensive voice, destructive voice) in elite sport teams.MethodPlayers from six field hockey and seven korfball teams from the two highest national levels were assessed for four weeks. Using social network analyses, players’ personality was related to their self-reported voice frequency, their voice frequency as perceived by all teammates (other-ratings), and the extent to which they pass on voice.ResultsExtraversion was positively related to players’ frequency of positive and negative voice. Other traits such as conscientiousness and emotional stability were only related to, respectively, positive or negative types of voice. Not all personalities (e.g., extraversion) were consistent in how they assess their own voice versus how others perceive this. Interestingly, traits such as extraversion, emotional stability and the agentic facet of narcissism were found to predict the passing on of voice.ConclusionThis study explored the importance of personality for (a) players’ frequency of a differentiated set of positive and negative voice and (b) the extent to which they function as ‘gates’ that more covertly pass on voice. Further, the results provide perspective on how specific personalities view their voice behavior versus how their teammates perceive their voice behavior. In this way, this study is a first step in identifying players who have the potential to endanger or strengthen a team in a clear or subtle, yet influential way.     

Beyond the molar-molecular distinction: we need multiscaled analyses.

Dinsmoor's (2001) adherence to molecular analyses may require him to assert that molar and molecular principles are mutually exclusive, but to instead analyze the phenomena of avoidance as inherently multiscaled is to follow a well-established practice in the natural sciences. Besides the issue of scale, two-factor theory, which Dinsmoor advocates, has little to say about some important and longstanding results in experiments that qualify as avoidance.     

New York City young adults’ psychological reactions to 9/11: findings from the Reach for Health longitudinal study

This research examines psychological distress among 955 economically disadvantaged New York City residents surveyed during high school and again after the September 11th terrorist attacks (9/11), when they were young adults. As part of the longitudinal Reach for Health study, young adult surveys were conducted from 6–19 months post-9/11 (average 8 months), providing opportunity to assess types of exposures and psychological distress, including symptoms of post-traumatic stress disorder (PTSD), depression, hopelessness, and anger. Regressions of psychological distress on 9/11 exposure were performed, controlling for high school distress, prior exposure to violence victimization, and socio-demographic characteristics. Exposure to 9/11 was positively associated with anger, hopelessness, and PTSD symptoms and a measure of global distress. The relationship was greater among women for PTSD symptoms. Although those who reported high school distress also reported more distress in young adulthood, prior psychological distress did not moderate the relationship between exposure and psychological outcomes. Greater exposure is related to distress among those who, during high school, reported lower distress, as well as among those who reported prior greater distress.     

Infants' interactions with professional caregivers at 3 and 6 months of age: a longitudinal study

This study longitudinally investigated the quality and stability of 64 infants’ interactions with their professional caregivers in child care centers at 3 and 6 months of age, i.e., across the first 3 months after they entered child care. It was also examined whether the infants’ negative emotionality (as rated by the mother) predicted the quality of the caregiver–infant interaction. The interactive behavior of the professional caregivers (sensitivity, cooperation) and the infants (responsiveness, involvement) was rated from videotapes recorded in three different caregiving situations, lasting about 25 min in total. In contrast to our expectation, the quality of the caregiver–infant interaction did not significantly increase across the first 3 months in child care. As expected, significant rank order stability was found for the quality of the caregivers’ behavior over time. Also in accordance with our expectations, infants with higher negative emotionality scores experienced less sensitivity and cooperation in interactions with their primary professional caregivers at both ages.     

Longitudinal Behavioral and Academic Adjustment in Children with HIV Infection

This study investigated; the behavioral adjustment and academic status of children with HIV infection through serial evaluations over a ten-year period. The parents of children were assessed with Achenbach Child Behavior Checklist Parent Forms and the children were administered the Woodcock-Johnson Tests of Academic Achievement at regular intervals as part of their treatment in the HIV Program of a children’s hospital. Children with HIV were found to have behavioral adjustment within normal limits over time. Aggressive behavior was noted to decrease over time. Academic achievement mirrored IQ status, unlike other studies, which have reported poorer achievement than expected for IQ. Math skills appeared to improve over time. Thus, these findings suggest children with HIV infection did not show significant behavioral disturbance across time, however, aggressive behavior appeared to decrease. Academic achievement was stable over time.     

The Influence of Bloomfield's Linguistics on Skinner

Bloomfield''s “Linguistics as a Science” (1930/1970), Language (1933/1961), and “Language or Ideas?” (1936a/1970), and Skinner''s Verbal Behavior (1957) and Science and Human Behavior (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities between the two authors were found. In particular both asserted that (a) the study of language must be carried out through the methods of science; (b) the main function of language is to produce practical effects on the world through the mediation of a listener; and (c) a physicalist conception of meaning. Their differences concern the subject matter of their disciplines and their use of different models for the analysis of behavior. Bloomfield''s linguistics and Skinner''s functional analysis of verbal behavior are complementary approaches to language.
